Annealing Furnaces Working Principle
Annealing is a heat treatment process that is used to alter the chemical or physical properties of a metal to make it more ductile and reduce its hardness. An annealing furnace works by heating an annealing furnace above its recrystallization temperature and then cooling once the sample has been maintained at this temperature for a suitable ...
